Vue集成百度地图实现位置选择
- 需求:添加门店时,需要选择门店的省、市、区、详细地址、以及门店的经纬度信息。
- 解决方案:集成百度地图API,通过在地图上搜索或者点击获取门店的具体位置信息。
百度地图选择地址效果
具体效果如下图所示
集成百度地图的具体实现
技术方案: Vue + ElementUI + 百度地图 JavaScript API v3.0
工程目录结构图:
```
ProjectName // 项目名称

第一步:引入百度地图 JavaScript API v3.0 文件
修改文件:public -> index.html
<script type="text/javascript" src="http://api.map.baidu.com/api?v=3.0&ak=你的秘钥"></script>
第二步:编写百度地图选择位置组件
新增文件:src -> components -> BMapAddressSelect -> index.vue
<template>
<el-dialog title="位置选择" :visible.sync="openMap" width="900px" append-to-body>
<el-form label-width="80px">
<el-row>
<el-col :span="10">
<el-form-item label="搜索地址">

</el-form-item>
</el-col>
<el-col :span="14">

</el-row>
</el-form>
<div id="baidu-map-container" style="width: 100%; height: 400px;"></div>
<div slot="footer" class="dialog-footer">
<el-button type="primary" @click="confirmSelect">确 定</el-button>
<el-button @click="cancel">取 消</el-button>
</div>
</el-dialog>
</template>
<script>
export default {
data() {
return {
searchAddresKeywords: "",
addressInfo: {
// 地址信息
longitude: "", // 经度
latitude: "", // 纬度
province: "", // 省
city: "", // 市

methods: {
// 初始化百度地图
initBaiduMap() {
let that = this;
this.$nextTick(function () {
var map = new BMap.Map("baidu-map-container"); // 创建地图实例
var point = new BMap.Point(116.404, 39.915); // 设置中心点坐标
map.centerAndZoom(point, 13); // 地图初始化,同时设置地图展示级别
map.enableScrollWheelZoom(true); //开启鼠标滚轮缩放
// 添加地图点击事件
map.addEventListener("click", function (e) {
var clickpt = e.point; // 点击的坐标
map.clearOverlays(); // 移除地图上的标注
var marker = new BMap.Marker(clickpt); // 创建标注
map.addOverlay(marker); // 将标注添加到地图中
// 逆地址解析
that.geocAddress(clickpt);
});
// 建立一个自动完成的对象
var ac = new BMap.Autocomplete({
input: "searchAddres",
location: map,
});
// 鼠标点击下拉列表后的事件
ac.addEventListener("onconfirm", function (e) {
map.clearOverlays(); // 移除地图上的标注
var local = new BMap.LocalSearch(map, {

onSearchComplete: function (results) {
let poi = results.getPoi(0); //获取第一个智能搜索的结果
var searchpt = poi.point; // 获取坐标
map.centerAndZoom(searchpt, 16);
map.addOverlay(new BMap.Marker(searchpt)); //添加标注
that.geocAddress(searchpt); // 逆地址解析
},
});
// 搜索词
var searchValue = e.item.value;
local.search(
searchValue.province +

});
});
},
geocAddress(point) {
let that = this;
var geoc = new BMap.Geocoder();
geoc.getLocation(point, function (geocInfo) {
// 设置基本信息
var addressInfo = geocInfo.addressComponents;

let address = addressInfo.street + addressInfo.streetNumber;
if (geocInfo.surroundingPois.length > 0) {
address = address + geocInfo.surroundingPois[0].title;
}
that.addressInfo.address = address;
});
},
show() {
this.openMap = true;
this.initBaiduMap();
},
confirmSelect() {
this.$emit("confirmMapAddress", this.addressInfo);
this.openMap = false;
},
cancel() {
this.openMap = false;
}
},
};
</script>
<style lang="scss">
// 防止地图自动完成的对象被遮挡
.tangram-suggestion {
z-index: 9999;
}
</style>
第三步:使用百度地图选择位置组件
<template>
<div class="app-container">
<el-row>
<el-col :span="12">
<el-form ref="addressInfo" :model="addressInfo" :rules="rules" label-width="100px">
<el-form-item label="门店地址" prop="address">
<el-input placeholder="请选择门店地址" v-model="addressInfo.address" disabled>
<template slot="prepend">{{addressInfo.province}}{{addressInfo.city}}{{addressInfo.district}}</template>
<el-button slot="append" icon="el-icon-map" @click="showMap" type="primary">选择地址</el-button>
</el-input>
</el-form-item>
<el-row>
<el-col :span="12">
<el-form-item label="门店经度" prop="longitude">
<el-input v-model="addressInfo.longitude" placeholder="请输入经度" disabled />
</el-form-item>
</el-col>
<el-col :span="12">
<el-form-item label="门店纬度" prop="latitude">
<el-input v-model="addressInfo.latitude" placeholder="请输入纬度" disabled />
</el-form-item>
</el-col>
</el-row>
</el-form>
</el-col>
</el-row>
<!-- 百度地图位置选择 -->
<BMapAddressSelect ref="bmapAddressSelect" @confirmMapAddress="confirmMapAddress"></BMapAddressSelect>
</div>
</template>
<script>
import BMapAddressSelect from "@/components/BMapAddressSelect/index";
export default {
data() {
return {
// 位置信息
addressInfo: {},
// 表单校验
rules: {},
};
},
components: {
BMapAddressSelect,
},
methods: {
showMap() {
this.$refs.bmapAddressSelect.show();
},
confirmMapAddress(addressInfo) {
this.addressInfo = addressInfo;
},
},
};
</script>
